I have smoked for 25 years, 1-2 packs a day, and I want to quit using Zyban and the e-cig. I've tried Zyban once before and while I smoked much less, it wasnt enough so I gave up after 12 days - stopped taking it and logged a fail. I have also had an e-cig for a year but 10 months of that it just sat in a drawer - couldnt replace the cigs with it enough to matter and I didn't really like it so I gave up.
I'm thinking that if I combine these 2, the effect will build up; however the doctor who prescribed the Zyban is against e-cigs, she was adamant I shouldn't use the e-cig - an advice I don't intend to follow.
I don't understand this all-or-nothing approach - maybe I am weaker than most, but one crutch wasn't enough, and I don't see why I can't use two crutches :). Especially since Zyban can be better with NRT, and the ecig is a form of NRT - one you can tailor to your needs unlike gum or patches.
I've quit once before for over a year, cold turkey, and it was so horrible it's been 12 years since I restarted (I know, stupid) and I still know I'd rather die than do that again
